Comprehensive education's flipping pursued (8)
I believe the answer is:
detailed
'comprehensive' is the definition.
(thesaurus)
'education's flipping pursued' is the wordplay.
'education' becomes 'ed' (abbreviation - e.g. sex ed).
'flipping' says the letters should be written backwards.
'pursued' becomes 'tailed' (tailing is a kind of pursuing).
'ed' back-to-front is 'de'.
'de'+'tailed'='DETAILED'
(Other definitions for detailed that I've seen before include "Particular" , "Minutely described" , "Exhaustive" , "Giving full particulars" , "Meticulous" .)
